Key identification features
- Large, torpedo-shaped body reaching up to 16 feet in old adults
- Gray-blue to grayish-brown back fading sharply to a white belly
- Long, conical, slightly upturned snout
- Five rows of bony scutes: one dorsal, two lateral, two ventral
- Four barbels arranged in a row ahead of the mouth
- Heterocercal tail with an elongated upper lobe
Common look-alikes
- Russian sturgeon: more robust and shorter-snouted, and native to the Caspian/Black Sea basins rather than East Asia, so range alone usually rules it out.
- Kaluga: a giant relative from the Amur River system with a much broader, more predatory mouth and heavier jaw than the Chinese Sturgeon's narrower tube mouth.
- Amur sturgeon: overlaps in general body shape but is confined to the Amur River drainage far north of the Chinese Sturgeon's Yangtze range.
Where you'll see one
Chinese Sturgeon are anadromous, spending most of their lives in coastal waters of the Yellow and East China seas before migrating far up the Yangtze River to spawn on gravel beds below Yichang. The species is critically endangered, and wild sightings are now extremely rare.
Frequently asked questions
How do I tell a Chinese Sturgeon from a Russian Sturgeon?
Body shape and geography both help: Chinese Sturgeon have a longer, more tapering snout and are found only in Chinese coastal waters and the Yangtze, while Russian Sturgeon are stockier and live around the Caspian and Black seas.
What is the most reliable field feature for a Chinese Sturgeon?
Look for the sharp contrast between a gray-blue back and a bright white belly combined with a long, evenly tapering snout and five distinct scute rows.
